Oregon State Police on Thursday posted a photo on Twitter that showed damaged cars covered by the gooey eels. The agency also posed the question: “What to tell the #drycleaner?”

Meanwhile, the Depoe Bay Fire Department posted a video of workers using a bulldozer to clear the eels from Highway 101.

Police said Salvatore Tragale was driving north with 13 containers holding 7,500 pounds (3,402 kilograms) of hagfish, which are commonly known as slime eels.

As Tragale approached road construction and tried to stop, one container flew off the truck bed and into the southbound lane, while the other containers spilled onto the highway, police said.

The flying container hit one vehicle which then caused it and four other vehicles to be pushed into each other. Police said the people in the vehicle hit by the container suffered minor injuries. No one else was injured.

When hagfish become stressed, they secrete a slime, which can be seen in the photos on the vehicles and on the highway, police said.

The road reopened after the bulldozing and hosing it off was completed Thursday afternoon.
